HORACE F. HUMPHREY, OF IOLIET, ILLINOIS.

WIRE-DRAWING APPLIANCE.

1 0 all whom it may concern Be it known that I, HORACE F. HUMPHREY, a citizen of the United States, residing at Joliet, in the county of Will and State of Illinois, have invented certain new and useful Improvements in Wire- Drawing Appliances, of which the following is a specification.

The present invention deals more particu larly with that portion of a wire drawing appliance or device relating to the means for controlling the rotation of the block and with the construction and arrangement of the safety appliance, whereby this control is actuated.

The objects of the present invention are to provide electrically controlled means which will operate to govern the rotation of the block; to provide a safety member which will be arranged to lie beyond the die stand and to provide a connection between this safety member or appliance and the means which govern the flow of electrical current to the means which govern the rotation of the block.

A further object of the invention is to provide a safety appliance of a form whereby it will lie, when positioned, adjacent and along the front and sides of the die stand.

The invention further consists in the fea tures of construction and combinations of parts hereinafter described and claimed.

In the drawings: Figure 1 is aview of the device of the present invention in operative position with respect to a wire drawing block appliance; Fig. 2 is a detail showing the front of the die stand with the safety appliance of the present invention in position; and Fig. 3 is a plan view of the safety appliance.

In the art to which the present invention relates, danger is encountered because of the fact that workmen become entangled in the wire passing to the die or between the die and block, and are drawn against the swiftly revolving block, with the result that they are either killed or dangerously injured. Owing to the speed of rotation of these blocks, and the passage of the wire, any safety appliance which may be provided must be of a nature to act immediately upon a person being thrown against the same, and the action upon the block must be immediate, or harm will be done before the block is stopped.

In the present invention, use is made of an Specification of Letters Patent.

electrical current to carry out the action of the safety appliance, it being well known that electricity is extremely quick of action, is powerful, and can be obtained in almdst any plant or factory.

Referring to the drawings, and particularly to Fig. l, the device is shown in connection with a wire drawing block 4 which is mounted upon a shaft 5 which is driven through the instrumentalities of suitable gearing 6. A bottom portion 7 is movable and constitutes a sort of clutch for communieating movement from the shaft 5 to the block l. Blocks of this nature are well known in the art, and it is understood that this particular form of block is shown only for illustrative purposes, and that the subjcct matter of the invention is not limited in application to this form of block, but may be used with any type desired and practical.

The means for raising and lowering the clutch portion 7 consists, in the construction shown, of solenoids 8 secured to a suitconnection 11 from any suitable source of electrical supply. The solenoids constitute one embodiment of electrically actuated means for controlling the rotation of the block. The wires of the electrical connection 11 are joined respectively to a movable contact 12 and a fixed contact 13, the mov able contact being carried by a sliding arm or bar 1%, attached to a pivoted member 15, which latter, as shown, extends adjacent the front and sides of "the die stand 1 1, and constitutes what may be termed the safety appliance or member.

The safety member or appliance 15 is pivoted at the point 16. Its method of use and operation is as follows: If an operator should be feeling the wire as it passes out of the die to the drawing block to discover the presence of burs, and should become entangled in the wire and be drawn against the stand and toward the block, he will strike the pivoted member 15, hitting either that portion 15 lying in front of the die stand or the portion 15 lying upon one or the other sides thereof; and by striking the same the upper end of the'pivotedmember 15 will be swung inward toward the block and the lower end will be swung outward, thus pulling the link or bar 14 outward, and thereby causing an engagement between the contacts 12 and 13, establishing a flow of current through the electrical connection 11, and energizing the solenoids which will operate to actuate the clutch portion 7 of the drawing block 4: and stop the rotation of the same. The stoppage of the block will be practically instantaneous and at the same time the operator is pulled against the safety member, and thus the block will cease its rotation before the operator has been carried forward and dragged into engagement therewith.

By forming the safety appliance so that it. extends ad acent the front and each side of the die block, provision is made whereby no matter how or in What manner the operator is dragged toward the revolving block, he will strike the safety member, so that, whether he happens to be at the front or side of the block when caught, it will make no difference, as he will strike the safety member in either case when pulled toward the block. If desired, a spring 17 may be employed for normally holding the safety member in position, as shown in Fig. 1, whereby the contacts 12 and 13 are nor.- mally out of engagement. The device, of course, is susceptible of modification and is not intended to be limited in any other manner than by the terms of the appended claims.

I claim:

1. In a wire drawing appliance, the combination of a wire drawing block, means for rotating said block, means actuated by an electrical current for controlling the rotation of said block, means for making and breaking the flow of current to sai controlling means, a die stand, shiftable means extending beyond the die stand and constituting a safety device, and a connection between said shiftable means and said current making and breaking means, substantially as described. I

2. In a wire drawing appliance, the combination of a wire drawing block, means for rotating said block, clutch mechanism for controlling the rotation of said block, solenoids for controlling said clutch, means for governing the energization of said solenoids, a die stand, shiftable means extending beyond the die stand and constituting a safety appliance, and a connection between said energy governing means and said shiftable means, substantially as described.
